Just replaced my TB gaskets, torqued to spec- started car and you can hear the boost leak, will barely hold idle. Tried tightening the bolts alittle higher but no luck. Is it normal for the 'spring' that holds the throttle cable to have in and out play in the TB assembly? I believe thats where the leak is coming from now.
 
I tried thats why I believe the boost is leaking from there, I didnt get any bubbles but I can hear it. Thats also why I made my question bold because if thats not normal then its probably the issue.
 
If its a big boost leak at the throttle body its most likely a vacuum as well. Try spraying the are you think is leaking with starter fluid. You don't have boost at idle so its a vacuum leak your most likely hearing. If its leaking where you think spraying it with starter fluid should make either rev up or die out. most likely rev though.
